Description

Technical Field

[0001] This invention relates to a power distribution system, and more specifically to a fully flexible power distribution system. Background Technology

[0002] Multi-terminal flexible DC power distribution system is a DC-dominated power distribution system. It utilizes the flexible DC technology of converters and the characteristics of flexible and controllable power flow to provide an effective solution to the problems faced by modern power systems, such as the access of new energy sources, efficient power supply to DC loads, and insufficient reactive power supply at load centers.

[0003] In flexible power distribution systems, existing products select DC input terminals based on the customer's current capacity and the number of power output lines. When the current capacity varies, different current input terminals need to be selected, requiring individual settings based on the current, which increases the cost of using the terminals. Summary of the Invention

The drive shaft is coaxially fixed to the shaft of the drive motor. The drive shaft passes through the center of all the drive wheels. A key block is slidably provided on the drive shaft. When the key block is embedded in one of the keyways, the drive shaft drives the drive wheel corresponding to the keyway to rotate.

[0009] As a further improvement of the present invention, the drive shaft is hollow and a piston is slidably disposed therein. The key block passes through the drive shaft and is fixed to the piston. A rotary air distribution valve is fixed to the end of the drive shaft facing away from the drive motor. An air source is provided on the outer wall of the drive housing.

[0013] The beneficial effects of this invention are that, by setting up the wiring base, front terminal, and rear terminal, a conductive path can be effectively formed by combining the front terminal, conductive module, and rear terminal.

[0019] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0020] Reference Figure 1 As shown, this embodiment of a fully flexible power distribution system includes power distribution equipment and terminals installed on the equipment. Each terminal includes a base 3, several front terminals 1, and several rear terminals 2. The front terminals 1 and rear terminals 2 are respectively connected to external power distribution equipment. A current sensor is connected to either the front terminal 1 or the rear terminal 2. An adjustment groove 4 is provided on the base 3, and several conductive modules 5 are disposed within the adjustment groove 4. The conductive modules 5 connect the front terminals 1 and the rear terminals 2. The base 3 is equipped with a drive mechanism to move the conductive modules 5. Device 6, the driving device 6 is connected to the current sensor, so as to drive different numbers of conductive modules 5 to connect the front terminal 1 and the rear terminal 2 according to the current detected by the current sensor. By setting the wiring base 3, several front terminals 1 and several rear terminals 2 and conductive modules 5, a current channel can be effectively formed by combining the front terminals 1, rear terminals 2 and conductive modules 5. Furthermore, the width of the current channel can be changed by changing the number of conductive modules 5 connected. At the same time, by setting the current sensor and the driving device 6, the effect of automatic adjustment based on detection feedback can be achieved.

[0021] As an improved specific implementation, the driving device 6 includes a plurality of driving conveyor belts 7 arranged in parallel within the adjustment groove 4. A plurality of conductive modules 5 are mounted one-to-one on the plurality of driving conveyor belts 7 and are driven by the driving conveyor belts 7 to slide back and forth within the adjustment groove 4. By setting up a plurality of driving conveyor belts 7, the operation of the driving conveyor belts 7 can be effectively used to drive the conductive modules 5 to slide back and forth within the adjustment groove 4.

[0022] As an improved specific implementation, the drive conveyor belt 7 includes a drive wheel 71 and a belt body 72 sleeved on the drive wheel 71. The conductive module 5 is fixedly installed on the belt body 72. The end of the wiring base 3 is fixedly connected to a drive housing 8. Several drive wheels 71 are rotatably arranged inside the drive housing 8. The end of the drive housing 8 is provided with a drive motor 9. The shaft of the drive motor 9 passes through the drive housing 8 and is linked with the drive wheel 71 to drive the drive wheel 71 to rotate. With the above structure, the rotation of the drive wheel 71 can effectively drive the belt body 72 to move, thereby driving the conductive module 5 to slide back and forth in the adjustment groove 4.

[0023] As an improved specific implementation, the drive wheel 71 has a drive shaft hole 711 at its center, and a keyway is formed on the wall of the drive shaft hole 711. The drive shaft 91 is coaxially fixed to the shaft of the drive motor 9. The drive shaft 91 passes through the center of all the drive wheels 71. A key block is slidably provided on the drive shaft 91. When the key block is embedded in one of the keyways, the drive shaft 91 drives the drive wheel 71 corresponding to that keyway to rotate. By setting the key block and keyway, it is possible to effectively realize that by moving the key block to embed in different keyways, the drive shaft 91 on the drive motor 9 drives different drive wheels 71 to rotate, thereby driving different belts 72 to move the corresponding conductive modules 5. In this way, it is not necessary to set up many motors to drive the drive wheels 71 to rotate one by one.

[0024] Reference Figures 2 to 3 As shown, in one embodiment of the drive shaft 91, the drive shaft 91 is hollow, and a piston 92 is slidably disposed inside it. The key block passes through the drive shaft 91 and is fixed to the piston 92. A rotary air distribution valve is fixed to the end of the drive shaft 91 facing away from the drive motor 9. An air source is provided on the outer wall of the drive housing 8. The air source and the rotary air distribution valve are connected through an air pipe to fill or draw air into the drive shaft 91, thereby driving the piston 92 to slide back and forth inside the drive shaft 91. Through the arrangement of the piston 92 and the rotary air distribution valve, the piston 92 can be effectively driven to slide back and forth on the drive shaft 91 using an external air source, thereby driving the key block to continuously embed into each keyway. This effectively drives the different drive wheels 71 to rotate, driving the belt body 72, and thus driving the conductive module 5 to slide in the adjustment groove 4.

[0025] Reference Figures 4 to 5As shown, in another embodiment of the drive shaft 91, the drive shaft 91 is hollow, and a slider 93 is slidably provided inside the drive shaft 91. The key block passes through the drive shaft 91 and is fixed to the slider 93. A motor is fixed inside the end of the drive shaft 91 facing away from the drive motor 9. A lead screw is coaxially sleeved on the shaft of the motor. The lead screw passes through the slider 93 and is threadedly connected to the slider 93 to drive the slider 93 to slide back and forth inside the drive shaft 91. With the above structure, the motor can effectively drive the lead screw to drive the slider 93 to slide, thereby driving the key block to slide back and forth on the drive shaft 91, and thus continuously connecting different keyways, thereby achieving the effect of driving different drive wheels 71 to rotate.

[0026] As an improved specific implementation, the wiring base 3 includes a front movable plate 31, a base plate 32, and a rear movable plate 33. The front movable plate 31 and the rear movable plate 33 are slidably disposed on the base plate 32, and an adjustment groove 4 is formed between the front movable plate 31 and the rear movable plate 33. By setting the front movable plate 31, the base plate 32, and the rear movable plate 33, the width of the adjustment groove 4 can be effectively adjusted. This allows the width of the adjustment groove 4 to be increased when the conductive module 5 moves, facilitating movement. After the movement is completed, the width of the adjustment groove 4 is reduced to clamp and fix the conductive module 5, ensuring the contact of the conductive module 5.

[0027] As an improved specific implementation, the front moving plate 31 is rotatably provided with adjusting screws 34 at both ends. One end of the adjusting screw 34 is inserted into the end of the rear moving plate 33 and threadedly connected to the end of the rear moving plate 33. By adjusting the screw 34, the front moving plate 31 and the rear moving plate 33 can be effectively driven to automatically move closer or further apart. In this way, it can cooperate with the drive motor 9 to realize the automatic movement and adjustment of the position of the conductive module 5.

[0028] In summary, the fully flexible power distribution system of this embodiment, through the setting of front terminal 1, rear terminal 2 and conductive module 5, can effectively form a conductive path by using a front terminal 1 and a rear terminal 2 and then connecting the conductive module 5 between the front terminal 1 and the rear terminal 2. Then, by changing the number of conductive modules 5 connected, the width of the conductive path can be effectively changed, thereby achieving the effect of adaptive current.
